The Wizard Project

The Wizard project is a result of my long-term work in construction of large gliders. It was thought of as an instrument for flight research, focusing on induced drag and assisting my work in finding solutions to improving flight performance on the large gliders. Small gliders are much more sensitive to anything interfering while flying which made them perfect for research purposes.

As a long-term pilot of 4.0m wingspan F5J and F3J models, I was surprised how much harder flying 1,5m wingspan models was. My first expression was that at attempts for tide turns the model would stall much sooner than expected.

I spent long hours at the airport doing hands-on aerodynamic analysis to find the causes leading to the stalls.

My research suggested that the main cause for the stalls are the vortex at the ends of the ailerons.

After testing different types of constructions, I developed the triangular end of the ailerons. It reduces the harmful influence of whirlwinds at acceptable technological complexity.

My research led to the creation of the F3K Wizard. Its flight properties are like the ones of larger gliders without unexpected stalls, with improved control and improved efficiency. The body shape is based on my many years of research into aerodynamics on larger gliders.

Curiosity leads to the continuous search for improvement. And this is one infinite magical process.

At Ston Models, we believe that glider design is as much an art as it is engineering. With Shaman, our newest F3K creation, we set out on a journey to surpass expectations: to feel every thermal, to respond with precision, and to soar higher, longer, and more beautifully than before.

Shaman is inspired by the Wizard, reimagined – sharpened, refined, tuned. We’ve taken what worked and pushed it further. New airfoils calculated for the very best F3K performance, a refined fuselage design, and modifications all around for sensitivity, control, and efficiency.

Optimized for Thermals. Every detail has been considered: the aileron shape, wing design, and fuselage modifications are all intended to respond gently yet sharply to rising air. Shaman wants to feel the lift — and reward the pilot who can sense it.

Smart Construction & Practical Design. New load‐bay for ballast gives you flexibility: adjust to strength of lift without compromising balance

A new wing-fuselage electrical connection with spring contacts makes setup easier and more reliable.

Two-piece wing mounted on top, secured with four screws—secure, quick to assemble, and strong.

Rudder shape updated for better control; the elevator retains the dihedral style you loved from Wizard.

Balanced Between Performance & Usability. We didn’t sacrifice ease for speed. Shaman remains accessible, intuitive, and built to last — perfect for serious hobbyists and competitors alike, anyone who dreams in lift, bank, and the whisper of wind under the wings.

Who is Shaman For? For pilots who want to elevate their F3K play. If you hunger for responsiveness, subtlety in soft lift, wings that don’t stall unexpectedly, controls that feel alive — Shaman is made for you. Whether in competition or simply chasing that perfect thermal, this is your tool for finesse.

Imagine launching into a gentle early‐morning sky. The wing catches a lift, just enough… then another, and you rise. Shaman tracks true. It responds. It climbs. In those moments, flight is no longer just maneuvering — it’s magic.

At Ston Models, evolution never stops. The original Shaman opened a new chapter in F3K soaring – now, with Shaman 2 and Shaman Evo, we take it even further. Faster response, sharper control, limitless customization – these models are built to let you choose how you want to fly.

Shaman 2 – Agile, Balanced, and Versatile

After months of testing and refinement, Shaman 2 arrives with a new fuselage design:

Shorter nose, improved geometry, and a re-engineered tail angle for greater agility and precision.

Ballast capacity up to 150 grams, giving the model exceptional performance in windy conditions.

Tail options: a dihedral elevator and a classic flat elevator, with the option to configure it with two flaps for even more control.

Shaman 2 is about balance — forgiving yet sharp, reliable yet thrilling. The perfect upgrade for pilots who want to push their flying further.

Shaman Evo – For Advanced Pilots Who Demand More

Designed for those who seek the cutting edge:

A completely new fuselage with inverted V-tail and top-pull control.

Flown exclusively with two flaps, the Evo offers extreme agility — capable of rotating almost around its own axis.

Configurable with 5 servos for maximum performance, or a lightweight 4-servo version using our in-house mechanical mixer (combining elevator and rudder). The 4-servo setup saves weight while still delivering competitive performance, though with reduced programming flexibility.

Shaman Evo is precision unleashed — designed for experienced pilots who know how to program, fine-tune, and squeeze every last drop of performance from their glider.

Wings That Unite the Family

Both Shaman 2 and Shaman Evo are fully compatible with the original Shaman wings. No matter which fuselage you choose, you can trust the proven aerodynamic excellence of the Shaman wing system.

Made for You

We know every pilot is unique. That’s why both Shaman 2 and Shaman Evo are offered with:

Wide range of colors, including stunning pearl finishes.

Multiple design styles – from elegant simplicity to bold, high-contrast competition schemes.

And most importantly: custom designs on request – we love bringing your personal vision to life.

Shaman 2 or Shaman Evo — your flight, your choice.

Whether you value stability in the wind, agile precision, or the freedom to define your own style, the Shaman family gives you the tools to fly the way you dream.
